As
Ash Borer Claims More Trees, Researcher
at ISU Works for Species Survival (Sep
10, 2009) Iowa State University.
A researcher and horticulturist
at Iowa State University is collecting and
storing seeds for several species of trees,
including ash, for the USDA's National Plant
Germplasm System. The seed stocks can serve
as a national source for reintroducing ash
trees once the devastation from the Emerald
Ash Borer can be controlled.
